Did you ever notice the Cornucopia in the middle makes it kind of seeem like a sundial because the sun goes around the arena (like it does around the earth) and since the cornocopia is in the middle creates a shadow to show the current time. I think the reason why Katniss at first didn't know this is because the arena was a circle to Katniss since it was probably sometime at night (11:00 to 12:00pm maybe) and the sun wasn't shining on it to look like a sundial.

well they didn't expereince it but they did see a body ripped apart and the aircraft had to take several trips to pick up all the body parts of the person that got ripped apart. so Peeta just wrote on the leaf "beast"

ooooohhhhhhhhhhh...........you mean the JABBERJAY part. mockingjays cant mimick voices they just mimick sounds.it was the Jabberjays that mimicked the voices of people that katniss and Finick knew, screaming.and yes it was bad because it did fuck with their minds, you do have a point their.now i get what you were asking. also, remember the part where katniss's wedding dress turned into a mockingjay. well i dont get it, how could Katniss "BE the mockingjay"????that just doesnt make that much sense to me.
